Laser Cladding

A precise method of adding a protective layer to components using powder or wire feedstock. Results in: metallurgical bonding; improved wear, corrosion, and heat resistance; and dimensional restoration of worn parts. The laser melts a thin layer of the substrate surface simultaneously with the incoming feedstock, creating a fully fused, metallurgically bonded deposit — distinct from thermal spray or weld overlay coatings that rely on mechanical adhesion or shallower fusion bonding.

Laser Hardening

Uses a focused laser beam to locally heat and transform the microstructure of the surface layer: non-contact, precise surface hardening; no need for quenching media; ideal for gears, cams, and shafts. The laser heats the surface to austenitising temperature in a precisely controlled, localised zone; the surrounding cold bulk material then rapidly self-quenches the heated zone through conduction, eliminating the need for external quenching media (oil, water, polymer) that conventional induction or flame hardening requires. This self-quenching mechanism produces a precisely bounded hardened zone with minimal distortion to the surrounding component geometry.

Laser Welding

Joins materials with a narrow, high-energy beam: deep penetration welds with minimal distortion; suitable for reflective and dissimilar materials; clean, strong joints for critical assemblies. Within the integrated 5-axis platform, welding completes the trio of processes available without repositioning the workpiece — a component can be clad to restore worn material, hardened at specific functional zones, and welded to join or repair features, all within a single fixturing setup.

Core System Components

• High-Power Laser Source (Fibre, Diode, or Disk): selected to match the specific material and process combination — cladding, hardening, or welding — required for the application
• 5-Axis CNC Motion System: maintains optimal beam orientation across freeform surfaces, edges, and complex contours for all three integrated processes
• Powder or Wire Feedstock Delivery System (for cladding): precisely meters and delivers cladding material to the melt pool, coordinated with laser power and travel speed
• Process-Specific Optics and Beam Shaping: configures the beam characteristics appropriate to cladding, hardening, or welding mode
• User-Friendly CNC Software with CAD/CAM Integration: manages multi-axis motion coordination, process parameter switching, real-time monitoring, and automated parameter setting
• Fume Extraction and Safety Enclosure: maintains operator safety and process environment cleanliness across all three process modes
• Emergency Stop Functions and Interlocks: ensures compliance with international laser safety standards during multi-process operation

Multi-Functionality

Performs laser cladding, hardening, and welding in one system. This integration boosts productivity and eliminates the need for multiple specialised machines — a single capital investment and floor space allocation addresses three distinct surface engineering and joining processes that would otherwise require three separate machines, each with its own footprint, operator training requirement, and maintenance schedule.

Ultra-Precise Motion Control

The 5-axis design ensures precision processing of complex parts with minimal motion errors and high repeatability. This precision is the foundation for consistent results across all three process modes — uniform clad layer thickness, consistent hardening depth, and reliable weld penetration — on the freeform and compound-curvature components common in turbine, die, and precision component applications.

High Power Laser Sources

Compatible with fiber, diode, or disk laser sources to match material requirements and ensure high performance across diverse applications. This source flexibility allows United Spectrum Instruments to specify the laser technology best matched to each customer’s primary process and material requirements — fibre lasers for general cladding and welding versatility, diode lasers often favoured for hardening applications due to their beam profile characteristics, and disk lasers for specific high-power cladding requirements.

User-Friendly Software Interface

Intuitive CNC controls with: real-time monitoring; CAD/CAM integration; and automated parameter setting. This software architecture reduces the process expertise burden on operators — material and process presets configure validated parameters automatically, while real-time monitoring provides quality assurance feedback during processing across all three process modes.

Robust Safety Mechanisms

Equipped with: safety enclosures; fume extraction systems; and emergency stop functions and interlocks. This integrated safety architecture ensures the multi-process platform meets international laser safety standards regardless of which of the three processes — cladding, hardening, or welding — is in operation, each of which generates different process by-products (metal vapour and powder overspray for cladding, minimal by-products for hardening, weld fume for welding) requiring appropriate extraction and containment.

Aerospace Industry
